Strawberry Vandal

I think I have a strawberry vandal. 

 Many of the tires' strawberries look as they should.

 But some look as if something has chomped everything off next to the soil. Maybe deer are the culprit.

 But some of them have round holes coming up from the bottom.  Moles make round holes but don't eat leaves.  Voles use mole tunnels but eat the entire plant, leaving nothing.  I don't know what is destroying them.
